HINGE.

SPECIFICATION forming part of Letters Patent No. 690,782, dated January '7, 1902.

' Application fina Ju1ys,19o1. serialNo. 67,004.. (Numan.)

To a/ZZ whom it may concern:

Be it known that I, JAMES G. SMITH, a citizen of the United States, residing at Covington, in the county of Kenton and State of Kentueky, have invented certain new and useful Improvements in Hinges; and I do declare the following to be a-full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeanduse the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in: hinges, and especially to a hinge comprising a pint-le carrying plate which has a double spiral-'or inclined Way on a lateral extension' of said plate and about a central boss carryi ng the pintle and the provision of two com plernental platesections,one of which has integral-therewith a hollow'partitioned box, one compartment of which containing a spring-.actuated plunger carrying an antifriction-wheel designed to travel upon the inclined Way, the .other compartment ot' which has its inner Wall circular in outline and formingabearing-surface forthe pintle, While the two complemental plate sections have their rear longitudinal edges curved toward each other and heldin contact, the inner faces of the plate-sections being adapted to embrace the opposite sides of a door to which the plates are secured, thus enabling the latter to swing in either direction and to be held normally in a closed relation. f

To these ends and to such others as the in-4 vention may pertain the same consists, fur-- ther, in the novel construction, combination,

` and adaptation of parts, as will be hereinafter more fully described and then specifically defined in the appended claim.

My invention is clearly illustrated in the 'accompanying drawings,-in whichlThe plate-sectionA2 has its rear longitudi-` nal edge inwardlyeurved and is notched, as at a, so as to allow said curved' edge to extend over the upper `fiat portion ot' the projection a distanceequal to one-halt thewidth of said projection. AInFignl this curved edge is shown as extending over and in contact with the upper flat portion ofjthe extension. Integral with the inner .wall of-the plate-section A2 is a box H, having a hollow compartment I, in which the plunger H3 Works. This plunger has a stem H2, which works through and is guided in an aperture through the top 'of said boX. Interposed between the plunger and the top of the box and about said stern is a coiled spring H', and between thelugs F2 on the bottom of the plunger is mounted the antifriction-wheel F. The cylinder-compartment E of the box is tted over the pintle, as shown in Fig. l, and a pin E holds the platesection A2in place on the pintle.

The second plate-section A3, having the lugs A4,with threaded sockets therein, is of a shape substantially like plate A2, having an inwardly-curved rearlongitudinal edge,which when fastened to the plate A2 by means of bolts, (not sl1own,) which are designed to pass through the holes in plate A2 and engage the threaded sockets A4, with a door intervening between said plates A2 and A3, contacts with the curved edge of plate A2, thus forming a casing about the pintle and the'boxing turning thereon.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is

A double-acting hinge, comprising the stationary plate A having a lateral extension B, a central boss on the latter, an inclined and spiral track about said boss, the pintle seated IOO in athreaded hole in said boss, the two coming portion of said box resting on said boss Io plemental plates A2 and A3, notched as deand against'a concaved shoulder of the extenscribed and having their rear longitudinal sion,as shown and described.A

edges curved toward each other and held in In testimony whereof I hereunto affix my contact over said extension, the box on the signature in presence of two witnesses.
